ATTACHMENT FOR WATER-GAGES.

PEOIFIGATION' forming part of Letters Patent No. 662,732. dated November27, 1900.

Application filed July 3, 1900.

To (ti/Z whmn 7'15 may concern.-

3e it known that I, WILLIAM MARTIN Mc- LEIsH, a citizen of the UnitedStates, and a resident of New Albany, in the county of Floyd and Stateof Indiana, have invented a new and Improved Shut-Off and Alarm, ofwhich the following is a full, clear, and exact description.

The invention relates to steam-boiler watergages; and its object is toprovide a new and improved shut-off and alarm arranged to immediatelyshut oli the Water and steam in case the gage-glass breaks and to givean alarm at the same time by blowing a whistle, and thereby calling theengineers attention to the accident.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a perspective view of the improvement as applied. Fig. 2 isan enlarged sectional plan view of the gage-glass and clip, and Fig. 3is a section on line 3 3 of Fig. 1.

The water-gage on which the improvement is applied is provided with awater-inlet pipe A and a steam-inlet pipe 13, connected with each otherin the usual manner by a gage- C, said pipes being provided with theordinary valves D and E for opening and closing the pipes whenever it isdesired to insert a new glass 0.

In the pipes A and B and next to the boile are arranged cut-off valves Fand G, respectively, and having the arms F' and G of their 1 valve-stemsconnected with each other by a rod H, carrying a weight I. The valves Fand G may be of any approved construction;

$erial No. 22,447- LNo modeLi ranged in such a manner that when the armJ rests on the support K the valves F and G are in an open position. Incase the gageglass 0 breaks and the support K drops from under the rod Jthen the weight I on the rod H causes the latter to move downward, sothat a swinging motion is given to the valve-stem arms F and G to closethe valves F and G, and thereby shut oil the water and steam in thepipes A and P.

In order to prevent: the clip K from being lost, ashort chain K connectsthe clip with one of the protecting-rods N, arranged adjacent to thegage-glass C.

In order to sound an alarm at the time the gage-glass breaks, the upperend of the connecting'rod H is connected by a chain 0 with theoperatinglever P of a whistle P of any approved construction andconnected with the pipe B between the boiler and the valve G. Thewhistle P is normally closed; but when the rod H moves downward, aspreviously explained, then the chain 0 imparts a swinging motion to theoperatinglever P, so that the whistle P is sounded at the time thevalves F and G are closed, thus calling the attention of the engineer orother attendant to the accident.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A water-gage, provided with shutoff valvesin the steam and water inlet pipes, a weighted connection between thevalves for holding the latter normally open, a support on the gage-glassand engaged by the connection, whereby the said connection will besustained until the glass breaks, and a whistle connected with saidconnection, and set in operation upon the downward movement of thelatter, as set forth.

2. A water gage, provided. with shut-off valves in the steam and waterinlets, a weighted rod connecting the valve-stem arms with each other,an arm on said rod, and a support on the gage-glass adapted to supportthe free end of said arm, as set forth.

A water-gage, provided with shutoff valves in the steam and waterinlets, a weighted rod connecting the valve-stem arms with each other,an arm on said rod, a support on the gage-glass adapted to support saidarm, a Whistle, and a connection between the whistle and said rod, asset forth.

4. A Water gage, provided with shut-off valves in the steam and waterinlet pipes, a connection between the valves for holding the latternormally open, a support on the gagevglass for sustaining saidconnection until the glass breaks, a whistle connectedwith saidconnection and operated upon the downward movement of the latter, and aretaining devicefor connecting the said support with one of theprotecting-rods of the gage so as to prevent the latter from being lostwhen the gageglass breaks, as set forth.
